1. Cookie: Cookies are small variables that store data about the current user. Cookies are set by the Web server, and are subsequently sent by the client browser with each request that matches the domain and path attributes (if set) set for the cookie. Unless explicitly set to persist via the Expires cookie attribute, a cookie will be destroyed when the user closes their browser.
   Cookies may be used to track and store information such as user name, user password and what parts of the site were visited.
2. Database management system: Programs that control the organization, storage and retrieval of data for multiple users. Examples of database management systems are Oracle, Sybase, and DB2.
3. Enterprise resource planning: ERP (enterprise resource planning) is the practice of using client/server technology, mainframes, and relational databases to manage all aspects of a business. As the name suggests, it involves planning the business, but it also covers ways to manage the manufacturing process, make purchases, as well as manage the important parts of its business, including project planning, human resource planning, supply chain management, inventory management, and order tracking. ERP is designed to lower supply chain costs, reduce the need for large amounts of inventory and enable a manager to conduct real-time checks of his/her company's manufacturing and business processes.
   The most popular ERP suite of programs is sold by a German company named Systems, Applications and Products in Data Processing (SAP). Its latest product, the R/3 series, traditionally worked with mainframes, but is now heavily involved in the client/server model, including Linux.
4. Legacy system: A computer system or application that continues to be used when the cost of replacing or redesigning it is prohibitive.
5. Middleware Software systems and utlities that provide a service and sit between the client and backend databases or legacy systems.
